ENDURO-SPECIFIC WHEELS AND TIRES: Cross-country-spec Dunlop® Geomax® AT81 tires front and rear are ready to head straight to the races. An 18-inch rear tire has a taller sidewall to improve comfort and reduce pinch flats.

Engine

GNCC®-TUNED YZ125 POWER: Based on the legendary 125cc liquid-cooled, reed-valve-inducted YZ two-stroke engine, the YZ125X utilizes a revised compression ratio, Yamaha Power Valve System (YPVS) timing, and a model-specific CDI unit—all focused on creating broad power delivery that suits off-road terrain and a wide range of rider skill levels.

REVISED POWER VALUE: The YZ125X features the patented Yamaha Power Valve System—with broader opening timing compared to the motocross version for smoother power—to create a smooth balance of power across the rev range.
